The ubiquitous electron-transport protein cytochrome b 5 can serve as an effector (activator or inhibitor) of P450s. It was hypothesized that cytochrome b 5 is involved in the transfer of the second electron to P450, either from CPR or from NADH:cytochrome b 5 reductase (CBR; EC 1.6.2.2):
In the process of oxidative phosphorylation, a globular cytochrome cc protein is involved in the electron transfer from the membrane-bound complex III to complex IV. Complex III itself is composed of several subunits, one of which is a b-type cytochrome while another one is a c-type cytochrome.
